When Metatron casts the angels out of Heaven, it is not a rogue reaper that comes after Cas, but a siren.
Snippet:
Cas shook his head vaguely, no longer as adamant about keeping his lips turned away from the siren. "This…it…it isn't real," he hissed, several teardrops escaping from his eyes. Never in all his years of existence had he felt so utterly torn in two. His body wanted what the siren offered, but his heart was breaking with the knowledge of what it would mean.
"Real's a matter of perspective, Cas. Real or not real, this is what you need right now. Besides, you know you'll never be with the real Dean Winchester. Deep down…you know this is what you deserve. You deserve to be punished…and to die like a dog."
"Why are you doing this?" Cas asked, turning his face up to look the siren in the eye, their lips barely inches apart. He wasn't fighting anymore. "You can take what you want any time."
"No," the siren said softly, breath ghosting across Castiel's lips. "I'm not going to force you, Castiel. You're going to choose it, and that's the point. I didn't have to give myself away. I could've had you twice by now, completely willing, without a drop of venom. I wanna see the great Castiel choose to fall into damnation, with full understanding of what it means when you do. So kiss me, little angel, and you and me'll hold hands and sail off this cliff together," the siren said, its voice a perfect imitation of Dean's most seductive growl.
The creature's grip on his wrists had loosened, but Castiel did nothing with that knowledge. For what could have been an eternity, he just stared up into those piercing green eyes – eyes that he'd loved longer than he'd even understood what love was – and they gazed back at him with all the love and desire he'd ever dared to hope Dean could feel for him. He remembered the first time he'd ever gazed into those eyes in Hell. Dean – on the verge of becoming a demon – gaze dark and dangerous, but even after everything, still hopeful, still needing him.
Save me, Cas.
With that, the former angel slipped completely over the edge.
